Salinity intrusion is one of the major water-related problems in the coastal region of Bangladesh. The intention of this study was to discuss the spatial distribution of soil and water salinity with their severity levels using geospatial techniques. The spatial analysis shows about 222 300 ha of new land being affected by various degrees of soil salinity during the last four decades. The analysis revealed that the spatial extent of salinity has been following an increasing trend and the movement of soil salinity has moved north from the coast. An increasing trend of salinity concentration in the rivers has already been found in the Lower Meghna River, Alaipur Khal (creek) of Daratona River, Gorai Madhumati, Rupsa Passur River and Bishkhali River in different districts of coastal Bangladesh. The groundwater is contaminated with a high level of salinity, which affects sources of drinking water, agriculture and the irrigation sector. Increased soil and water salinity levels cause an unfavourable environmental and hydrological situation that restricts usual crop production throughout the year. This research will assist decision makers and planners in taking proper initiatives for developing integrated land and water resources management plans for the coastal regions, which have similar environmental settings along the Bay of Bengal.

The choice of irrigation water sources is crucial in rice farming as water availability and cost can vary across water sources. Groundwater caters three-quarters of the total irrigated land in Bangladesh, where rice area alone occupies 80% of the total irrigated land. The present study compares productivity and ef ciency differences and determinants of surface and groundwater irrigation users based on a sample of 6947 dry-winter rice growing plots from the nationally representative Bangladesh Integrated Household Survey-2018 database. A range of methods was adopted to correct for heterogeneity in irrigation water source choice decision, self-selection and observable biases. This involved an estimation of a Stochastic Production Frontier (SPF) model with the pooled sample first, then an application of Propensity Score Matching (PSM) to remove self-selection and observable biases, then a test of heterogeneity in irrigation source choices was conducted, and finally estimated two SPF separately for matched samples of groundwater and surface water irrigation users. Results revealed a robust effect of groundwater irrigation in enhancing rice productivity and efficiency. Seed and its quality, fertilizer and soil type are also significant drivers of rice productivity. The significant drivers of efficiency are plot ownership, irrigation frequency, subsidy and family size. Large farms with groundwater-irrigated plots are relatively more efficient. Significantly lower efficiency exists in areas vulnerable to drought. These results raise sustainability concerns owing to the high level of groundwater extraction and falling water table. Policymakers need to devise innovative strategies to increase use of surface water irrigation without sacrificing productivity and efficiency, which has been a priority policy drive in Bangladesh.
